Description

200402359 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a coextrusion method of a multilayer composite structure. [Prior art] As shown by USP 5,122,905 and USP 6,982,025 by Wheatley et al., For example, it is repeated in the form of ABAB A cross comb flow having a layered structure and a layer and a layer B having different rheological properties, respectively, is known. Some such composite structures have been disclosed for providing excellent optical properties. The patent by Bank et al. Discloses other composite structures that provide gas barriers, cushioning, and resistance to fatigue fatigue. These composite structures include microlayer structures and have been disclosed because they can be manufactured using coextrusion. US patent usp442634u ^ by Dinter et al. On coextrusion, which includes a method of forming a laminated composite stream with a continuous but non-planar interface by setting the contact surfaces of the combined streams of the laminated composite . According to this manufacturing method, Dintel and others first form the laminated composite stream into different planes, and then rearrange the laminated stream into a coplanar relationship from side to side before combining the streams laterally, and then The flowing raw material is extruded from a downstream die to become a multilayer product. The second picture of the Dentle patent discloses a multi-layered product formed by combining two halves (as shown by the imaginary line in USP5094788, USP5094 7 93 and USP5269995 disclosed by Schrenk et al., The forming and laminating stream composed of separate continuous layer streams of different thermoplastic materials

λ · * > 200402359 V. Description of the Invention (2) Multiple interfacial surfaces are produced in a molten polymer stream. In the prior art of this type, a shaped laminated stream system flowing in the z-direction on the X-Y-Z coordinate system and including a substantially flat interface on the x_z plane is split into a plurality of branch streams. The operation of dividing the stream into a plurality of branch streams is performed along the X axis, and is substantially parallel to the Z axis, and the lateral dimension of the interface is defined by the X axis. Therefore, a plurality of tributaries can be obtained by separating and forming the interface of the laminar stream. The term "branch stream" used in this prior art refers to the layered stream obtained by separating and stacking the precursor streams' then 'the branch stream is redirected with respect to the X-axis and the γ-axis', making it a branch stream It is oriented in the stacking direction on the Y axis. Points of the redirect

The branch streams are combined in an overlapping relationship to produce an intersection branch stream containing a plurality of interfacial surfaces. The prior arts such as USP50 94788, 5094793 and 5269 9 95 also disclose separate adjustments of branch flow rates, and changes in the size of the X- and γ-streams. In addition, USP526 9995 mentions the use of a protective boundary layer to avoid the layer instability of the micro-layer co-extrusion process and the occurrence of fractures at the interface, in order to avoid the desired optical characteristics and / or Mechanical properties have an adverse effect. The disadvantage of the prior arts such as dry USP5094788 and 5094793 is that if the laminated stream has adjacent layers with different rheology, the interface may be distorted due to, for example, time dependent migration, and the layer body formed may be deformed or distorted. Another disadvantage of these prior arts is the instability of the interface of the living body; the protective second boundary layer used in the prior art of USP5269 995 adds an outer layer that is not desirable or unnecessary for the intended use. large

200402359

Furthermore, in the prior arts such as USP5094788 '5094793 and 526 9995, the final composite structure is limited to the cross comb layer structure, and the distortion of the layer may be exacerbated by the large mechanical adjustment of the forming stack flow. . 〃 Therefore, especially when the composite surname structure is processed from different thermoplastic materials, it is necessary to reduce its interface distortion and layer deformation and distortion ^. Moreover, it is necessary to reduce or eliminate the expansion of the layer-body interface instability. It is more ideal if this result can be achieved without relying on the protective boundary layer. Therefore, the adjustment of the abundant flow of the forming layer and the improvement of microlayer coextrusion can be improved. The compaction method is as expected. In addition, multi-layered composite structures including better barrier properties or better layered properties and more non-=== morphological = layered composite structures also have their needs. Composite structures = ::: such as ί or odor barriers are very useful. Better barrier pressurized bladder for different types. Weixia is also excellent as various types of packaging materials.

The relative orientations of the forming streams according to the present invention are changed to a forming stream and a spaced second orientation system, and the redirected stream is changed. then

The first stream is merged to form the boundary: the stream may be a layered stream containing at least one A-face, and the multiple streams are formed by combining the first plurality of streams "..." The material stream can be a layered material stream that includes even two = "" refers to the it interface of the project. The two or more of the two microlayers required for the co-extrusion process are used for the purpose of forming a laminated stream if necessary. In accordance with the method of the present invention, in volume flow rate or mass flow rate: use at least the net ten product or mass to be combined. The difference in warfare to control the stratification Or, any one of the streams or the two systems will not be reoriented: it can be a single stream. Based on the composition of dazzling fusion. '< Secret stacking or single layer, suitable, according to the manufacturing method of the present invention, since the first machine has a substantially along the X _ γ _ Z coordinate 幵 / stream and the second forming material direction, and the stream from the first In a preferred embodiment where the main flow direction of the relative direction is changed from T to T, the stream is directed along the main direction x and the second relative direction. In the newer orientation, a generally stacked orientation, at which the reformed streams are roughly side-by-side oriented, define the first plane along the Y axis, and from the moon avoidance direction, the first and second planes. In a roughly side-by-side orientation, the two-to-one forming stream defines a second plane. [Of course, there may also be other: the streams may be the same or in the same way. The forming and laminating composite is formed by the first $ -shaped stream and the second forming stream in a melt stacking method, thereby generating the aforementioned interface. According to the manufacturing method of the invention, unlike the prior art of USP5 094788, the formation of the laminated composite is not related to the shunting of the precursor flow of the laminated. Therefore, the first forming stream and the second forming stream can not only

As before, it can be different, and the number can be increased to produce more laminated composites. ^ 'The method of producing superimposed and superimposed streams, and the superimposed superimposed streams can also be used according to the rate or mass flow of the present invention. rate.

Then, according to the manufacturing method of the present invention, the forming layer is increased in size along the X axis to form an interfacial system with a width A over a thick object :: a wide multilayer composite.

IM 200402359 V. Description of Invention (7) Structure. Moreover, the present invention can provide a multilayer composite structure having more layers. As shown in FIGS. 1 and 2, the first laminated stream 12 including the interface 14 having a width W of the present invention is formed by the precursor streams A and B. The second lamination stream 22, which also contains the interface 24 having a width W ', is formed by the precursor streams C, D. As mentioned earlier, the additional layers required for the microlayer coextrusion process can continue to increase. Also, if necessary, more laminated streams can be formed.

Specifically, as shown in FIG. 2, the device 10 includes co-extrusion sub-mechanisms 26 a and 26 b, and the sub-mechanisms 26 a and 26 b form the precursor stream into a shape suitable for co-extrusion molding. Geometries of stacked streams 丨 2,22. The feed channel 15a is appropriately connected to the precursor stream a with an extruder (not shown) and a coextrusion sub-mechanism 26a. The stream A flows into the manifold 30a and then diffuses in the manifold ', and its diffusion direction substantially crosses the main flow direction of the stream A indicated by the arrow in the pre-converged flow path 34a. After passing through the flow forming channel manifold, 'stream A' enters the preconvergent flow channel 34a.

. Similarly, the feed channel 16a is appropriately connected to the precursor stream b (the extruder is not shown) and the co-extrusion auxiliary mechanism 26a's flow forming insert 2 & The flow path is after entering the manifold to 8 ** | diffusing in the manifold 'and the diffusion direction is approximately intersecting with the main flow direction β of the flow β located in the pre-convergent flow channel 44a * Xiao'. Through this & i stream B, it enters the pre-convergent flow channel 44a of the co-extrusion sub-mechanism 26a. π ^ θ The stream A and the stream B respectively flow out from the pre-converging flow channels 34a, 44a and the converging flow channel 46a of the pressure auxiliary mechanism 26a, and the forming flow has

Page 12 IHfKi 9 200402359 V. Description of the invention (8) Some widths correspond to the width W of the channel 34a and the width W of the channel 44a, respectively, and a fusion stack 12 is formed after meeting (as shown in Fig. 1). ), And an interface 1 4 (also has a width w) is included between the stream layers. Continue to refer to Figure 2 to explain other specific content. The feed channels 15b and 16b are appropriately connected to the extruder (not shown) for the precursor streams c and D and the co-extrusion auxiliary mechanism 26a, respectively. The streams C and D are typically different from each other in the direction of the rheological characteristics, and flow into the manifold 30b and the manifold 40b of the flow forming insert 2b, respectively. In each of the manifolds, the streams C and D are diffused respectively, and their diffusion directions substantially intersect with the main flow directions of the streams indicated by arrows in each of the pre-converged flow channels 34b and 44b. After passing through the flow forming channel manifold, the streams C, d enter the pre-converging channels 34b, 44b. Then, the streams C and D respectively flow out from the pre-converging flow channels 34b and 44b and meet in the converging flow channel 46b of the co-extrusion sub-mechanism 26b. The widths of the forming streams respectively correspond to the width W of the channel 34b, and The width W 'of the channel 4 4b. Moreover, after the fusion, a molten laminate 22 is formed (as shown in Fig. 1), and an interface 24 (also having a width W ') is included between the stream layers. It can be seen from FIG. 2 that the co-extrusion of the manifolds 30a and 40a of the secondary mechanism 26a can make the stream flowing out of the pre-convergent flow channels 34a and 44a have a width W, and the co-extrusion of the manifolds 30b and 40b of the secondary mechanism 26b can The stream flowing out of the pre-converging flow channels 34b, 44b has a width W ,. However, those skilled in this art should know that by increasing or decreasing the width of the material flow in each pre-convergent flow channel, the width W or W ′ downstream of the manifold can also be exchanged and set. Moreover, it is advantageous for the 'width W and W' to be substantially consistent with each other when the laminated streams 12, 22 are formed, but those skilled in the art should understand that when the laminated streams 1 2, 2 2 are formed, the width W may be greater than or

9489.ptd Page 13 i 200402359 V. Description of the invention (9) is smaller than the width W ′. The relative volume of the layers of each of the stacked streams 1 and 22 can be controlled using the relative volume flow rate. As described in U.S. patent USp5389324 to Lewis, 'Typical techniques for controlling relative volumetric flow rate include the use of temperature differences to affect relative flow = degrees' and the use of substantial differences in the length, height, and / or width of each flow path, for example. It is controlled by the geometric conditions of the runner, so as to form a multilayer with a thickness change of the body.体 物。 Structure. According to the present invention, the relative output volume of each extruder can also be used to control the relative volume of the layer body. Once it is very easy to make the output of the extruder of the stream B significantly larger than the output of the extruder of the stream a, it is very easy. As a result, when the streams A and B form the laminated stream 12, the flow volume is substantial. different. Therefore, as shown in Figure i, the volume of the? Layer is significantly larger than that of the A layer. If necessary, the relative stacks or relative mass flow rates can be used to make the melt stack (stacked stream). The layer A or stack in the layer A in 2 is larger, or as shown in the stack stream, each stack The masses can be substantially equal. In addition, as shown in FIG. 1, the geometric boundary 2 has a thickness approximately perpendicular to each of the interfaces 14 and 24, respectively, as shown in the figure), a square, or a thickness greater than the width. No ... may 'According to the present invention, the buckets 12, 22 may facilitate subsequent fusion and lamination operations. The so-called proper forming to facilitate succession: melting and combining or proper forming to facilitate co-extrusion, means that the flow stream to be at least includes a flat surface to achieve the characteristics of the two channels or flow forming inserts, such as channels or =

9489.ptd Page 14 200402359 Description of the invention (ίο) A flowing stream of at least one flat surface.

As can be seen from the above, according to a preferred embodiment of the present invention, the forming and laminating stream including a continuous and substantially flat interface having a width W is formed by combining the forming streams having the same width W, and including a continuous shape having a width w. The forming laminated stream with a substantially flat interface is formed by combining the forming streams having the same width w. Therefore, unlike the previous techniques of Schirrenk et al., The forming and stacking streams for forming the forming and laminating composite structure by melt lamination are formed independently. Therefore, in the manufacturing method of the present invention, there is no cascaded precursor stream shared by the streams 1 2, 2 2 and when the cascaded precursor stream 丨 2, 3 3 is formed, the cascaded precursor stream does not need to be split, so it does not belong to the branch stream . Therefore, the control of the layered flow is reduced, and there are advantages in that the interface is distorted and the layer body is less deformed and distorted. Referring again to FIG. 2 ', the co-extrusion sub-mechanisms 26a, 26b together constitute a co-extrusion mechanism. The co-extrusion mechanism 26 is divided into sub-mechanisms 26a, 26b by a partition 28. Regarding the partition 28, its elongated portion 28a partitions the manifold (30a, 30b), the pre-convergent flow channels 34a, 34b, and the convergent flow channels 46a, 46b. In addition, the elongated portion 28a of the partition provides a side wall 32a of the manifold 30a, the pre-condensed flow channel 34a, and a side wall 32b of the pre-condensed flow channel 34b, and a side wall (not shown) Show). Furthermore, the partition includes an arm portion 28b which is adjacent to and extends between the molding inserts 2a, 2b. In this way, in the drawing, the arms whose directions substantially intersect the elongated portion 28a are able to separate the manifolds 40a, 40b and the pre-convergent flow channels 44a, 44b of the inserts 2a, 2b, and provide the manifold 40a and the The side wall 32b of the condensing flow channel 44a, and the side wall 32b of the manifold 40b and the precondensing flow channel 44b (not

9489.ptd Page 15 200402359

The separator uses a detachable partition. The inserts 2a, 2b are also removable from the device j. Removability is not a practical separator. The board is more advantageous. Similarly, the removal of the mobile body is more advantageous. However, it is more advantageous to arrange the necessary separators of the practical flow forming mechanism relative to the center of the cross-pressing mechanism. Can make mutual

n = For example, the manifolds: 3, 3 which are identical to each other in the direction crossing the flow direction, and the channels 46a, 46b which are also identical to each other in the direction crossing the flow direction. Following on from the second picture of Participation and Participation, the channels a and 46b adjacent to each other are connected to the flow sequencer 50, and more specifically, the flow is connected to the flow sequencer 50 through the inlets 5ja and 52b. Sort channels 54 &, 54b. The flow sorting channels 54a, 54b are changed from the common planar side-by-side orientation at the entrances 52a, 5 2b when the convergence-forming interface generation channel 53 is changed to become a stacked orientation. As will be described later, like the partition 28 and the insert, the flow sequencer is also detachably inserted into the cavity of the device body.

See Figure 1 and the X-γ-Z orientation of the above system. X, γ, and z are oriented substantially perpendicular to each other in three directions. At the inlets 52a, 52b of the sequencer 50, the generally rectangular laminated streams 丨 2, 22 are suitable to be arranged side by side along the X axis. In the flow sequencer 50, the shaped streams 1 and 22 flow approximately in the main flow path or the X direction, respectively, and the interfaces 14 and 24 thereof are substantially aligned with the X axis and approximately

9489.ptd Page 16 200402359 V. Description of the invention (12) It is perpendicular to the Y axis. According to the present invention, the shaped stream is oriented and sorted in the sequencer 50 by the flow sorting channel and 5 stoves during the period of approximately flowing in the z direction, and changes from the side-by-side orientation along the X axis to the stacking orientation, as in the aforementioned usp The branch stream in the 509 ^ 88 patent and the first figure of the case is the same. In this stacked stream, the shape stream 12 defines a first plane, and the shaped stream 22 defines a second plane along the Y axis. As mentioned above, the main flow direction is defined as the z direction, because ΐ „like the X and Y axes change with the main flow direction ?, the reorientation of the streams 12, 22 along the X axis and ^ is as described above. The person skilled in the art can also see that as long as one material, the flow is along the X axis and the orientation is sufficient. 1 Φ Consider Figure 1 to Figure 3 'Interface of Sequencer 50 to generate channel 53 in the' Applicable to Melt-stacked reorientation materials, bonds, and combinations are formed along the main plane defined by / by the X-Z plane of the γ system, and a Λ stack of forming layers is formed. In the laminated composite 62, such as the one by Schirrenk and others; = According to the two, it can be known that the present invention does not stack the precursor stream, and the formation of the composite layer I: The separation of the shared layers 12 and 22 does not matter. The forming and stacking precursor stream of 62 is as shown in Fig. 1. In the forming and stacking, compared with stream 12, the stream 22 is from the valley or mass of the combined body 62, relative volume or relative quality: Quite a large proportion. For example, to control the former flow rate. Material flow =; accumulated flow rate or relative output of the extruder required for quality A and B is . The output stream is naturally more married laminate composite formed into the laminated interface most generating channel 53 Z - laminating stream flow of the substance 1 2,2 2

2475 200402359 V. Description of the invention (13) The dynamic volumes are different. If necessary, the relative volumetric flow rate or mass flow rate can be used to make the forming stream of the forming laminated composite 62 more volume or mass than the forming stream 22, or make it opposite, or substantially equal. The forming streams 12, 22 are substantially equal to each other in width, and the edges of the stream 2 are aligned with the edges of the stream 22 when forming the interface. Following this, reference is made to FIG. 2 again. The formed laminated composite 62 passes from the flow sequencer 50 to the connection passage 56 ending in the outlet groove 57 of the device 10 through the size conversion passage 55. More precisely, as shown in FIG. 3, the interface generating channel 53 is extended to the outlet groove 58 of the flow sequencer, and then is formed in the channel 55 including the opposite wall 59 which is oppositely arranged to increase the width of the flow. The layer 62 has an increased width before being discharged from the device 10. The phase of the composite body '$ width can reduce the width ratio of the composite body 62 to the downstream mold. After "2", according to the present invention, the forming and laminating composite system directly enters the appropriate conventional downstream extrusion die from the device 10, and the pressure shown in Fig. 1 is sent out by this die. If necessary, the " The next or two-composite 62 can be formed by condensing a similar stream on a ^ rQ g formed in the same way. Continuing to refer to FIG. 1, the composite reveals a free-flow extrusion die. It is stated that the width w greater than the thickness t is added to the mold of Dintel et al. The increase of the width is usually caused by the extrusion 64 parallel to the interface 64 generated by the flow sequencer 50. Generally, the degree w of Dinta is noted. A practical extrusion die, U.S. Pat. No. 4,426,344 for four people, whose i-th view is such a big view k T8, U 丨 Jin 丨 does not describe Dintel and other products, t However , The interface formed in Fig. 2 of the patent case of Tintel et al. And the interface formed previously are substantially perpendicular to each other

200402359 V. Description of the invention (14) ′ However, the interface 64 generated after the stream is redirected according to the present invention is roughly formed on the previously formed interfaces 14 and 24.

Therefore, according to the present invention, it is possible to obtain a multilayer composite structure including a layer body having reduced deformation or distortion and thereby improved performance. In addition, since the present invention does not require the use of branch streams, it is possible to obtain more composite structures with different layer combinations. For example, the four layers of the sheet-like structure 69 can be different from each other in characteristics, and are represented by A / b / C / D. Therefore, as disclosed by the previous technique of Schirrenk et al., A / B / Cross comb structures of C / D layer combinations can also be prepared. In particular, as shown in the embodiment of the device 31, it is not necessary to have a minimum limit or double the total number of layers in the generation of the interface. Moreover, when the present invention is applied to a microlayer coextrusion method, better effects can be obtained. The arrows located in the converging flow path 64a and the connection path 56 represent the main liquid flow directions from the formation of the streams 12, 22 to the time when the formed laminated composite 62 is sent out from the device 10. Each side plate (not shown) surrounds the coextrusion mechanism 26 and the rest of the exposed structure of the device 10, including the flow sequencer 50 and the downstream channel 5 6 °

In general, it is best to minimize any dimensional or shape changes to the shaped stack stream, as well as to avoid splitting the stack precursor stream (separation as described in the prior art by Schirrenk et al.). However, those skilled in the art will recognize that the forming stack stream can be appropriately modified to meet the needs of a particular process to obtain a product. Therefore, one or both of the forming stack streams 12, 22 can be adjusted in size before forming the interface 64. In addition, the shape of the laminated composite 62 can be changed to meet the needs of a specific process or product.

477 200402359 V. Description of Invention (15). As described above, the change in thickness and / or width is usually performed after the forming and laminating stream leaves the device 10. In this way, the adjustment of the shape of the lamination stream using the flow channel geometry can be reduced as needed. Refer to Figures 3 and 4. The flow sequencer 50 is preferably composed of a plurality of plates 76, 77, 78 showing surface channels 80, 81, 82, 83 on the plate surfaces 85, 86, 87, 88, respectively. These plates are combined to form Flow sequencing channels 54a, 54b and their inlets 52a, 5 2b. Entrance 52a and channel 5 4a are located at

The surface passage 82 of the surface 87 of the plate body 77 and the opposite surface passage 83 of the opposite surface 88 of the plate body 78 are formed. The surface passage 82 includes an inlet passage portion 90 and a convergent flow promotion passage portion 91. Similarly, the entrance 52b and the passage 54b are formed by a surface passage 80 located on the surface 85 of the plate body 76 and an opposite surface passage 81 of the opposite surface 86 of the plate body 77. The surface passage 81 includes the inlet passage portion 9 2 and convergence flow promotion channel section (or exit channel) 9 3. Continue to refer to Figures 3 and 4. The interface generating channel 53 and the outlet groove 58 of the flow sequencer 50 are formed in part by a plate 77 (Fig. 4). The alignment pins and corresponding holes (not shown) are very helpful for the alignment of the plates γ 6, 7, 7, 8 and the surface channels.

* Referring to FIG. 5, according to the present invention, the first five-layer fused stack 11 2 including the interface 114 with a width of ¥ is formed by a precursor stream. Similarly, the second five-layer fusion stack 1 2 2 including the interface 124 having a width W 'is also formed by the precursor stream. Referring to FIG. 6, the device 11 () shown in the figure is not the same as the device shown in FIG. 2; the difference is mainly in the co-extrusion auxiliary mechanism 126 & and 12 ^ to form a co-extrusion mechanism to form five Layered fused stacks 112, 122. on

200402359

The auxiliary mechanism includes three additional forming inserts (only the inserts n3a, mb, 1G4a, Di, and 1Q5a are disclosed in the figure). The precursor stream is separated by the partition 128 when it enters the coextrusion auxiliary mechanism. Like forming inserts 〇 02 1 〇 2b and flow sequencer 丨 50, these partitions are preferably formed by being removable by the device 10. As described above, it is generally preferred that the separator be disposed at the center of the inside of the coextrusion mechanism that intersects with the flow direction. As shown in FIG. 6, most structures of the forming inserts 103a, 103b, and 105a are indicated by dashed lines to highlight these inserting systems and other forming inserts. One = placed in the cavity of the body of the device 110. Some parts of the aforementioned structure and other aspects have been stated in the foregoing with reference to Figure 2. Therefore, the same ^ is represented by the same symbol, and the statement of device 11 is also omitted. The inner valley can be referred to Liwen for details. Description of device 10. The feed-through 115, 116, 117, 118, and 119 are suitable for connecting the co-extrusion mechanism of the extruder and the device 110, so that the precursor stream A; D and E enter the co-extrusion respectively as shown in the figure. mechanism. The precursors of the precursor streams can be different from each other, but in any case, the stream bc is preferably _ 5 and the feed A, respectively, and the stream]) and E are preferably different from the streams B and 匸, respectively.

Then, the diverted stream A spreads in the manifold, 1 3 0 b in a direction substantially intersecting with the main direction of the stream A ', as shown by the arrow in the pre-flow channel 134a, and enters the pre-concentrated circulation at the same time. 34a, 134b.

200402359 V. Description of Invention (17) Continue to refer to Figure 6 and Figure 7. When the precursor stream b flows from the feed channel 11 6 into the co-extrusion mechanism, the stream B is divided by the dividing wall 1 3 6 b of the partition 丨 2 8, and the dividing wall 1 36 b is formed in the partition On the arm portion 128b of the first cross bar 143a. Then, the divided stream 6 is dispersed in the manifolds 140a and 140b of the forming inserts 102a and 102b in a direction substantially crossing the main direction of the stream b, as shown by the arrows in the pre-convergent flow channels 144a and 144b. At the same time, they enter the pre-convergent flow channels 144a, 144b. The arm portion 128b extends and is disposed adjacent to the inserts 102a and 2b. In this way, the arms 1 2 8 b are able to form the manifold 1 4 〇 a,

140b is separated from the pre-converged flow channels 144a and 144b, and forms a side wall i32b of the manifold 140a and the pre-converged flow channel 144a, and a side wall (not shown) of the manifold 140b and the pre-converged flow channel 1 4 4b. The side walls of the manifolds 140a and 14b are convergent to form the shunt wall 136b. Similarly, when the precursor stream C flows from the feed channel 117 into the co-extrusion mechanism, the stream C is divided by the dividing wall 136c of the partition, and the dividing wall 136c is formed on the first cross rod of the partition. H3a is on the opposite arm portion 128c. Then, the diverted stream c is dispersed in the divergent members 1 4 2 a and 1 2 3 b of the forming inserts 103 a and 10 3 b, and the direction of the divergence is related to the pre-converged flow channel 4 4 a,

The flow directions indicated by the arrows in 1 4 4 b roughly intersect, and then enter the pre-convergent flow channels 138a, 138b. The arm portion 128c extends and is disposed adjacent to the molding inserts 103 and 103. In this way, the arms 28c can separate the manifolds 42a, 142b and the pre-converged flow channels 138a, 138b of the forming insert, and form the manifold 142a and the side wall 132c of the pre-converged flow channel 138a, and the manifold 142b and the pre-converged flow channel. Convergence Channel 138bt

200402359 V. Description of the invention (18) Side wall (not shown). The side walls of the manifolds 1 4 2 a and 1 4 2 b are in a convergent form, and constitute the split wall 1 3 6 c. Similarly, the precursor streams D and E also enter the co-extrusion mechanism of the device 10 through the feed channels 11 8 and 11 9. The feed channels are connected to the manifolds of the flow forming inserts via inlet channels. Figure 6 only shows the forming inserts (104a, 104b, 105a), inlet passages (127a, 127b), and manifolds (131a, 131b, 135a), but the forming inserts, inlet passages, and manifolds related to the forming inserts 105a Guan et al. Were not revealed.

Refer to Figures 6 and 7 again. When the precursor stream D enters the co-extrusion mechanism from the feed channel Π8, the stream D is divided by the dividing wall 1 3 6 d of the partition 1 2 8, and the dividing wall 136 d is formed in the second part of the partition 1 2 8 d of the arms of the cross bars 丨 43b. Then, the diverted stream d flows through the inlet channels 127a and 127b and diffuses in the manifolds 131a and 131b of the forming inserts 104a and 104b. The direction of the divergence is approximately the same as that of the pre-converged flow channels 1 4 4 a, 1 The flow direction indicated by the arrow in 4 4 b crosses, and then enters each pre-convergent circulation (the pre-convergent flow channel 145a is only partially revealed in the figure).

The arms 1 2 8 d extend and are adjacent to each other between the forming inserts. As a result, the arm portion 128d can separate the inlet channel (127a '127b), the manifold (131a, 131b), and the pre-convergent flow channel of the forming insert, and form the inlet channel. The side wall 133d of the 27 & The side wall I32d of the flow channel i45a, the side wall (not shown) of the inlet channel 1271), and the side wall (not shown) of the manifold 1311) and the pre-converged flow channel (not shown). The side walls of each inlet passage are in a convergent form to form a shunt wall 136d. The orientation of the cross bar 143b shown in the figure is the same as that of the first cross bar approximately crossing the elongated portion 128a of the partition member.

inOi 200402359 V. Description of the invention (19) The same 'for example, the drive stream E flows from the feed channel 11 to the forming inserts of the co-extrusion mechanism (the figure only shows a part of the insert 105), and is divided by a partition The diverging wall 1 36e of the opposite portion 1 28a is diverted. Then, the diverted stream E flows through each inlet channel, and then diffuses in each manifold (only part of the ^ manifold 135a is shown in the figure). The direction of the divergence is related to the pre-converged flow channel U4a, as shown by the "inner arrow" The directions roughly intersect, and then enter each of the pre-convergent circulations (only part of the pre-convergent flow channel 1 41 a is shown in the figure).-Pre-convergence of the diverted streams A, B, and C from the co-extrusion mechanism 1261) The flow channels 134a, 144a, and 138a flow out and merge in the preconvergent flow channel H6a. The width of the forming stream is preferably equivalent to the width w of the channel 134a, respectively, and a three-layer fusion stack is formed after the / lu combination. The stack contains its width phase, when the downstream stream that has been split at the layer interface of width W, that is, streams D and E exit from each of the pre-convergent flow channels 145a, 145b of the co-extrusion subsidiary mechanism 丨 26a, And the common channel 146a is merged with the previously formed three-layer fused stack. The formed streams D and E have a width equivalent to the channel 13 "width W_. After the merge, a five-layer fused stack is formed 112 (not shown in Fig. 5) 'its interface 114 also has a width w. Similarly, the divided streams A, B, and C flow from the co-extrusion auxiliary mechanism = ^ convergence flow channels 134b, 144b, 138b, and merge in the pre-convergence flow channel lj6a. The formed flow has the following characteristics: The width is preferably W ′, which is equivalent to the channel 13 stoves. After the merger, a three-layer fusion stack is formed. The width of the interface is equivalent to the width? . The divided downstream stream, ^-namely, the materials jD and E are discharged from the pre-converging flow channels (not shown) of the co-extrusion auxiliary mechanism 1261), and are melted in the common channel 1461} and the previously formed three-layer melting Stack

έ H Q 么 200402359 V. Description of the invention (20)-Combination and merger. The interfacial width of this fused laminated body is equivalent to w. Each width of the formed streams D and E is also equivalent to the width w of the channel 1341). After the merger, a five-layer fusion stack i 22 is formed (as shown in Figure 5), which contains The interface also has a width w ,. It can be seen from FIG. 6 that the manifold of the co-extrusion auxiliary mechanism 126b is used to provide a pre-convergent flow channel (the width of which is w) from the co-extrusion auxiliary mechanism 126b. Similarly, the manifold of the co-extrusion sub-mechanism 126b is also used to provide the stream flowing out of the pre-convergent flow channel (whose width is W) from the co-extrusion sub-mechanism 126b. However, 'for example, by increasing or decreasing the width of the flow in each pre-convergent flow channel, the width W or W downstream of the manifold can also be set interchangeably. Referring again to FIG. 5, the five-layered material flow 2, 122 having a defined geometric shape has a thickness t substantially perpendicular to the interfaces 114, 124, respectively. If necessary, the forming stream 11 2, 1 2 2 can be wider than thick (as shown), square, or thicker than width. If necessary, the relative volume or mass of the layer can be changed by changing its volume flow rate or mass flow rate. In any case ', according to the present invention, the streams 11 2, 1 22 can be appropriately formed in accordance with the subsequent molten laminate. Therefore, according to a preferred embodiment of the present invention, a five-layer forming stream 11 2 including a continuous flat interface 11 4 having a continuous shape with a width W is formed by combining forming streams having the same width W; The five-layer forming stream 122 having a continuous and substantially flat interface 124 having a width w is formed by combining forming streams having the same width W ′. Since the former drive stream is split in this embodiment, the streams 11 2, 1 22 have the same layer sequence. If necessary, for example, the device 1 1 0 of the embodiment shown in FIG. 2 can be supplied in the precursor stream.

200402359 Description of the invention (21) is changed, so that the streams 11 2, 1 22 are different from each other in the order of the layers. In this case, the streams used to combine to form the laminated stream 丨 2 The streams that are combined to form the stacked streams 1 2 2 may be identical in composition and different in composition. In addition, the difference in the output of the extruder can be used to change the relative volume or relative mass of the five-layer forming stream in the subsequent ten-layer forming composite. Gutz refers to the coordinate system of the X-γ-z axis in Fig. 5 and Fig. 6 at the inlets 152a, 152b of the flow sequencer 150, and is appropriately shaped so as to melt the superimposed lamination stream 11 2, 1 2 2 along the X axis. Side by side configuration. In the flow sequencer, the forming material flows generally along the main flow direction or the Z direction, and the interfaces 4 and 1 2 4. It is roughly aligned with the X axis. According to the present invention, the forming stream is redirected to the stacked orientation within the flow sequencer 150 as described in the stream 1 2, 2 2. In this orientation, the forming stream is defined along the γ axis. The spaced-apart different planes' and the ten-layer composite 162 formed by stacking the formed layers toward the γ direction produce a continuous, substantially planar shape interface 丨 6 4. Then, the shaped laminated composite 162 can smoothly pass through the flow sequencer and terminate in the continuous passage 156 of the outlet groove 157 of the device without changing the width or thickness. The arrows in the connecting passages 156 indicate the main flow directions of the streams 112, ι22 from the forming to the forming of the laminated composite 162 from the outlet of the device 110. As shown in Fig. 5, when the forming streams 2 and 1 2 2 are combined, they are substantially equal to the volume of the forming layer edge composite 16 2. However, the removability of the shape insert can change its flow rate, such as using one or more shape inserts with longer or shorter path lengths instead of pre-converging flow channels. Therefore, for example, the forming inserts 102a, 103a, 104a, and 105a can be exchanged for a long path of the pre-convergent flow channel.

200402359 V. Description of the invention (22) --- The much shorter 々 forming insert makes the volume of the forming stream 丨 2 much larger than the forming material 122, and thus forms the volume or mass of the forming laminated composite 162. This advantage can also be used to control the relative flow volumes of streams A, B, C, D, E in one or both of the stacked streams 112, 122. With this configuration, if necessary, any one or two streams with different layer thicknesses and even thickness variations can be produced. l < As for the present invention, as described in the related embodiments in FIG. 丨 and FIG. 2, the 々-shaped Yuefeng complex 162 is directly or indirectly entered into the downstream by the device 10, and then multiple layers are pushed out by the extrusion die. Sheet structure. _ = = After: = width is greater than thickness. The interface created after the cardia is approximately parallel to the width of the sheet body. The mechanism is co-extruded by the auxiliary mechanism 226 & after the three cross bars 2 are co-extruded, and the device ㈣ is also included in the package /; 228 also includes the first , 209. These plug-ins are also inserted into the cavity of the body of the device 2 10 in the same manner as other plug-ins and stream-forming plugs 208.

In the figure, the plug-ins and the flow chamber of the device 210 are omitted or clearly visible with the characteristics of ff. It is indicated in the flow direction. As described above, they are placed at the center of the co-extrusion mechanism, so that the directions in which the co-extrusion pair 1 intersects with the direction of substantially coordinated movement are substantially equal to each other. 26a, 226b and current

If you want to know about the device, please refer to the relevant descriptions of the above devices 1 0 and 11 〇. The feed channels 215, 216, 217, 218, 219, 220, and 221 are connected between the extruder (not shown) and the co-extrusion sub-mechanism of the device 21Q, so as to enable the precursor streams A, B, C, and D. , Β and G can enter the co-extrusion mechanism as shown in the figure. The rheological characteristics of these precursor streams are preferably different from each other, but 'in either case, the streams B and C and a are different, the streams and £ are different from the streams B and C, and the streams are different. F and G are respectively associated with streams D and ^: different ways of matching are better. Like the device 110, the five-layer fused stack with a width equivalent to the width W of the channel 2 44a and a defined geometric shape is a suitable pre-converged flow channel from the co-extrusion auxiliary mechanism 226a and has a width A forming stream equivalent to 1 degree W is formed in the convergent flow channel 246a. At the same time, it has a five-layer fusion stack with a width equivalent to the width W of the channel 244b and a defined geometric shape. It is derived from coextrusion. A suitable pre-convergent flow channel of the auxiliary mechanism 226b has a width corresponding to the width W, and the forming material flow is formed in the convergent flow channel (not shown). However, an embodiment in which an extra layer is added will be described below. The precursor streams F and G are co-extrusion mechanisms that enter the device 210 through the feed channels 220, 221, and these feed channels are connected to the manifolds of the flow forming inserts through the inlet channel 21m. The ones shown in the figure are only flow forming inserts (206a, 206b, 207a), inlet channels (211a, 211b), and manifolds.

The precursor stream F flows from the feed channel 2 2 0 into the co-extrusion mechanism, and is then divided by the arm portion 228f 'provided on the third cross rod 243c of the partition member 228 " iu wall 2 3 6 f . Then, the diverted stream ρ flows through the inlet channels 211a and 211b, and then diffuses after the manifolds of the forming inserts 206a and 206b (only a part of the manifold 225a is disclosed in the figure), and then enters each of the pre-convergent flow channels ( Only a part of the pre-convergent flow channel 239a is shown in the figure). The arm portion 228f extends and is adjacent to each other between the forming inserts 206a and 206b. In this manner, the arm portion 228f separates each inlet channel (2Ua, 211b), the manifold, and the pre-convergent flow channel of the forming insert. The arm portion 228f constitutes a side wall 233f of the inlet passage 211a and a side wall (not shown) of the inlet passage 211b. The side walls of each inlet channel are condensed and shaped. The flow 236f is the same. The precursor stream G is divided by the diverter of the opposite arm: (not shown) at the cross bar 243c of the partition.

Because the widths of the formed streams F and G are equivalent to the width W of the pre-convergent flow channel 244a, a seven-layer fusion stack is formed after the merger, and the fusion stack includes the same width as the width. W interface. When the shunted flow F and (; exit from the corresponding pre-convergent flow channels of the co-extrusion auxiliary mechanism 226b and are in each common channel with the width W of the pre-converged flow channel 244b that has been previously formed and is equal in width, The five-layer fusion stack is merged, and the widths of the forming streams F and G are respectively equal to the width W ′ of the channel 244b. Therefore, after the merger, a seven-layer type including an interface having a width equivalent to the width W ′ is formed. A fused stack. Therefore, according to a preferred embodiment of the present invention, a seven-layer fused stack having a defined geometry and including a substantially planar continuous interface having a width W is formed by combining forming streams having the same width w A seven-layer fused stack with a defined geometric shape and a generally planar continuous interface having a width W, is also formed by merging the forming streams with the same width boundary.

If necessary, when the input of the precursor stream is changed as shown in Figure 2 of the embodiment 2 0, also The seven-layer fused stacks are made different in the order of the layers. In this case, the streams used to combine to form one of the seven-layer fused stacks may be the same or different in composition Forms another seven-layer molten laminate stream.

Fourteen-layer, 256-layer laminated composite with outer skin. The outer skin layer is a classic choice, which enhances the function of the manufacturing process and / or xm. In each manifold, the stream S and the system diverge in a direction substantially crossing the main flow direction of each of the pre-convergent flow channels 266, 267 downstream. The main direction of the preconvergent flow channel 267 is indicated by arrows. The streams s and τ enter the pre-convergent flow channels 266 and 267 from the manifold, and when they are combined in the combined channel 268, the 'formed streams naturally correspond to the composite in width, and at the same time form a sixteen having a relative width. Layer forming composite. Then, the final composite obtained by the present invention is pushed out of the device 210 through the outlet groove 257, and then directly or indirectly into the conventional extrusion die downstream as in the previous embodiment, and the multilayer sheet structure is discharged therefrom. As in the aforementioned sheet-like structure 69, the sheet-like structure of this embodiment also has a width greater than the thickness.

The insert 30 is suitable for forming a forming stream having a width equivalent to the width W. Each precursor stream is typical The grounds are different from each other, so that different streams in the finished product are adjacent to each other.

The arm portion 3 2 8 c of the partition member 3 2 8 is preferably arranged adjacent to the inside of the flow forming insert ', so that the side wall 3 3 2 c of the manifold and the pre-convergent flow channel of the insert are formed. „The co-extrusion mechanism 326 is used for forming and converging the material streams A and D, including the manifold 330c and the pre-converging flow channel 334 of the forming mechanism 327, the flow forming channel and the converging flow channel provided by the flow forming insert. 346, when the streams a and _D flow out from the pre-convergent flow channels 3 3 4, 3 3 8 and merge in the convergent flow channels 3 4 6, the widths of the formed streams respectively correspond to the width W of the channel 334, After the merger, 'a melt-formed stream 3 1 2 comprising a layer interface 314 also having a width W is formed. The output of the extruder for stream A is significantly greater than the output of the extrusion of stream D. The result is The flow volumes of flows A and D are substantially different from the flow forming the melt stack 312. Therefore, as shown in FIG. 9, the melt stack 31 2 is characterized by a larger volume in the layer A than the layer j).
